| 4 | Rocko Release 11/2017 | ||
| 5 | ===================== | ||
| 6 | |||
| 7 | Moved qat support to separate layer | ||
| 8 | ----------------------------------- | ||
| 9 | Quick Assist Technology (QAT) is more middleware and should not be part of the | ||
| 10 | core BSP. The new layer can be found here: | ||
| 11 | https://git.yoctoproject.org/cgit/cgit.cgi/meta-intel-qat/ | ||
| 12 | |||
| 13 | Moved dpdk support to separate layer | ||
| 14 | ------------------------------------ | ||
| 15 | We had some requests to make DPDK standalone so that it could be included | ||
| 16 | without bringing in anything else from meta-intel, as it is not specific to | ||
| 17 | Intel(R) hardware. The new layer is located here: | ||
| 18 | https://git.yoctoproject.org/cgit/cgit.cgi/meta-dpdk/ | ||
| 19 | |||
| 20 | Added support for out-of-tree iwlwifi drivers | ||
| 21 | --------------------------------------------- | ||
| 22 | Backport-iwlwifi out-of-tree wifi modules are now available via meta-intel. | ||
| 23 | Backport-iwlwifi brings the latest iwlwifi drivers to almost any kernel | ||
| 24 | Note that mac80211 and cfg80211 backports are also necessary, which will most | ||
| 25 | likely cause incompatibility with other in-tree wifi drivers. | ||
| 26 | See https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi for more info. | ||
| 27 | |||
| 28 | Added support for out-of-tree ixgbe drivers | ||
| 29 | ------------------------------------------- | ||
| 30 | The out-of-tree ixgbe drivers bring ixgbe support to nearly any kernel. See | ||
| 31 | here: http://www.intel.com/network/connectivity/products/server_adapters.htm | ||
| 32 | |||
| 33 | Added an implementation of Secure Boot | ||
| 34 | -------------------------------------- | ||
| 35 | meta-intel now supports a simple Secure Boot implementation. This implementation | ||
| 36 | consists of a single binary consisting of an EFI stub, the kernel, an | ||
| 37 | initrd, and a kernel command line. The binary is then signed via keys defined by | ||
| 38 | the variables SECUREBOOT_SIGNING_KEY and SECUREBOOT_SIGNING_CERT. These keys | ||
| 39 | should match the keys embedded in your hardware's firmware. | ||
| 40 | See documentation/secureboot/README for more information on this feature. | ||
| 41 | |||
| 42 | Improved Yocto Project Compatibility status | ||
| 43 | ------------------------------------------- | ||
| 44 | The common layer should now be considered Yocto Project compatible - it should | ||
| 45 | no longer modify OE-core values when adding the layer to your bblayers.conf. | ||
| 46 | The meta-tlk layer is still not Yocto Project compatible, however. | ||
| 47 | |||
| 48 | Pyro Release 5/2017 | ||
| 49 | =================== | ||
| 50 | |||
| 51 | Changed default kernel provider from linux-yocto to linux-intel. | ||
| 52 | ---------------------------------------------------------------- | ||
| 53 | Linux-intel is an Intel(R)-maintained kernel based on the latest stable | ||
| 54 | branch, along with backports from upstream to better support Intel(R) | ||
| 55 | hardware. The intel-linux kernel also has a branch with the preempt-rt | ||
| 56 | patches applied, providing a preempt-rt kernel with no additional work. | ||
| 57 | |||
| 58 | Added QEMU support. | ||
| 59 | ------------------- | ||
| 60 | We now build several virtio drivers into the kernel by default, and | ||
| 61 | have qemuboot.conf files for intel-corei7-64 and intel-core2-32 | ||
| 62 | targets. This allows one to do basic testing on meta-intel images | ||
| 63 | without having to use hardware. The virtio drivers are added via | ||
| 64 | KERNEL_FEATURES_INTEL_COMMON. This prevents them from being added to | ||
| 65 | custom kernels by default. They can be removed by adding the | ||
| 66 | following to a conf or kernel bbappend file: | ||
| 67 | KERNEL_FEATURES_INTEL_COMMON:remove = “cfg/virtio.scc” | ||
| 68 | OVMF firmware is also built and can be used in order to emulate a UEFI | ||
| 69 | environment. A full runqemu command line for intel-corei7-64 could look | ||
| 70 | like this: | ||
| 71 | runqemu core-image-minimal intel-corei7-64 wic ovmf | ||
| 72 | |||
| 73 | Musl support | ||
| 74 | ------------ | ||
| 75 | Meta-intel is now compatible with the musl C library. You can specify musl | ||
| 76 | As your C library by adding the following to your local.conf: | ||
| 77 | TCLIBC = “musl” | ||
| 78 | Note: there is a known failure with DPDK. | ||
| 79 | |||
| 80 | X32 support | ||
| 81 | ----------- | ||
| 82 | The meta-intel layer can now build with the x32 tune settings in a multi-lib | ||
| 83 | setting, it will not work in as the primary MACHINE tune as the bootloader needs | ||
| 84 | to be built as a 64bit binary. The setup for this would be as follows: | ||
| 85 | require conf/multilib.conf | ||
| 86 | MULTILIBS = "multilib:libx32 | ||
| 87 | DEFAULTTUNE:virtclass-multilib-libx32 = "corei7-64-x32" | ||
